OAR@ICRISATMorphological, pathogenic and genetic variability amongst sorghum isolates of Colletotrichum graminicola from IndiaJLathaauthorKMathurauthorP KMukherjeeauthorAChakrabartiauthorV PRaoauthorR PThakurauthorA total of 18 isolates of Collectotrichum graminicola infecting sorghum in Andhra Pradesh and Maharashtra, India, were characterised and compared for morphological, pathogenic and genetic diversity. The representative single-lesion isolates and their derivatives varied significantly for morphological traits -colony colour, growth pattern and sporulation on oat meal agar medium. These isolates also exhibited significant variation for disease reaction on a set of sorghum differential lines in greenhouse tests. The isolates from the local sorghum cultivars were although different from those of CSH 9, they did infect CSH 9 indicating a virulence shift in the C. graminicola population from the local sorghum to hybrid CSH 9. Genotypic variation was studied using the random amplified polymorphic DNA (RAPD) technique. A set of six random primers could differentiate the isolates. The cluster analysis indicated a very high genetic variability among isolates of C. graminicola and amogg variants from a single lesion isolates in RAPD profile.Sorghum2002Indian Phytopathological SocietyArticle
